To al? whom 15 may concern.'

Be it known that We, GEORGE W. MAC- KEN'zrn, Jr., and RAYMOND CRowDEu, citizens of the Uni-ted States, residing at Beaver and Edgewood, respectively, in the counties of Beaver and Allegheny and State Aof ennsylvania, have invented certain new and useful Improvei'nents in Measuring and Dispensin Pumps, l'of which. the following is a speci tion.

Our invention relates to measuring and dispensing pumps for delivering gasolene or other liquids in'mea'sured quantities from .i secondary or measuring tank connected with a main reservoir or source of supply, and more particularlyto the measuring tank and its associatedpal'lts.

The improved measuring tank which is they subject of this application is adapted particularly for use. on apparatus similar to that described in Patent No. 1,242,831, MacKenzie and George W'. vMacKenzie, Jr.; October 9, 1917, in which-the liquid isacaused to flow into the transparent secondary or measuring tank by the formation therem.

central vertically adjustable conduit exi tends upwardly into the'l secondary or measv'exhausting mechanism is set vesse or source of supply, and suitable air :exhausting means is provided and adapted to exhaust thev air from the secondary tank when desired.

The central conduit is adjpshible to predetermined positions only,

and when set to a selected position, the air in motion thereby exhausting the air from the secondaryl tank and creating a partial vacuum .which 'will cause the liquid to flow into the measuring tank through the adjustable condui-'t until the air exhausting mechanism is stoppgd. `Appropriate indicia are provided secondary or #measuring tank on the transparent measuring tank so that the amount of liquid therein may be readily observed and ascertained.

A suitable discharge outlet is also provided in such a v position on the tank'that all the liquid must ilow'out. therethrough. "f/lihe pljincipal object of the present invention ist()l so constructl the transparent terminal engagingmembers as to provide an Specification of Letters Patent. Application led November 12, 1917.

In the drawings- Figure l is 'a vertical sectional view of a. pump, partly broken away, showing our improvedmeasuring tank and its associated mechanism;

Fig. 3 is an enlarged detail view of the upper portion of the tan-k 'showing the novel form of joint used.

,Referring non7 ings, the letter designates the hollow standard of `the pump casing. The nleasuring tank is designated as a whole by the letter A and comprises a cast metal base 2 supported on the standard a, a. cylindrical transparent casing 3, and acast metaltop member 4.

A conduit 5 extends upwardly through the standard a from a storageA vessel (not .-sliown) and passes tlhrough a stuffing box` 6 lnto the measuring tank'A, Conduit 5 is adapted to be raised or lowered and partially rotated by the handle 7, and to be held particularly to the drawi thro-wniout of en- A ems invention,
